Secondary Reference PRT Fluke 5615-12 Inconel 305mm -200C to 420C
Description
The high-precision Secondary Reference PRT Fluke 5615-12 Inconel 305mm -200C to 420C is a reference-grade platinum resistance thermometer designed to bridge the gap between primary laboratory standards and industrial process calibration. Featuring an Inconel 600 protective sheath (305 mm length, 6.35 mm diameter), the Fluke 5615 SRTS integrates a 99.999% pure platinum sensing element coil-supported in a ceramic casing to virtually eliminate thermal hysteresis. This professional secondary reference PRT probe delivers exceptional measurement precision with an accredited calibrated accuracy of ±0.012 °C at 0 °C and robust 4-wire current-potential construction across a wide operating range of -200 °C to 420 °C.
Application field
Applications and scenarios:
- Comparison calibration procedures in calibration dry-wells, baths, and metrology laboratories
- Secondary temperature standard verification for industrial temperature sensors and transmitters
- Precision temperature monitoring in pharmaceutical, aerospace, and chemical processing facilities
- Reference testing with Fluke 1529 Chub-E4, 1560 Black Stack, and 1502A Tweener readout units
